| Surface Structure and Properties of Complex Intermetallics Vincent Fournée1; 1INSTITUT JEAN LAMOUR, CNRS-UNIVERSITé DE LORRAINE, NANCY, France; PAPER: 318/SISAM/Regular (Oral) SCHEDULED: 11:45/Sat. 26 Oct. 2019/Dr. Christian Bernard ABSTRACT: Quasiperiodic structures exhibit long-range order like normal crystals, but lack translational symmetry. Quasicrystals were first discovered as a new class of intermetallic compounds, now comprising hundreds of members in binary and ternary systems. They usually adopt either the icosahedral or the decagonal point group symmetry. Later, quasicrystals were also found in soft matter systems and more recently, in a two-dimensional perovskite oxide thin film grown on a periodic substrate. The discovery of quasicrystals has led to a paradigm shift in crystallography and has attracted a large interest in the material science community, motivated by unexpected physical properties that could be linked to quasiperiodicity. This remarkable class of materials has also challenged our understanding of metal surfaces. An atomic scale description of their surfaces is especially important, as it forms the basis for understanding and predicting phenomena such as gas adsorption, metal epitaxy, and friction. Here we will review some key results on the characteristics of their surface structure and their physo-chemical properties [1-4]. References: [1] J. Ledieu, V.
